उत्तर

The component statements of the given compound statement are: 

1) \[x = 2\]  is the root or the equation \[3 x^2 - x - 10 = 0\]

2)  \[x = 3\]  is the root or the equation  \[3 x^2 - x - 10 = 0\]

The connective used is "and". So, both component statements must be true for the compound statement to be true. The statement "  \[x = 3\]  is the root or the equation  \[3 x^2 - x - 10 = 0\] "  is false. Therefore, the compound statement is false.
